So this may be a really, really simple question, but I am having trouble understanding something. I was curious what a turqoise wire is, so I did some reading and found out it is for a refnum. But, I cannot find out what a refnum actually is. I think it is a link to a specific control on the front panel, but then why use a reference instead of a property node, or even wire the control directly to a desired output?
Thanks,
